В статье описаны современные представления о патофизиологии СНсФВ с акцентом на причинах ремоделирования миокарда, а также представлены актуальные алгоритмы диагностики данного заболевания. Показано, что триггерами развития СНсФВ являются активация нейроэндокринной системы, низкоинтенсивное воспаление и миокардиальный фиброз. Гетерогенность этиологии и сложность патофизиологии СНсФВ способствуют пересмотру существующих диагностических подходов. На сегодняшний день для выявления больных СНсФВ предлагаются новые шкалы риска – HFA-PEFF и Н2FPEF, эффективность которых пока до конца изучена. Совместное применение методов визуализации и лабораторной диагностики обеспечивает комплексный анализ морфологического и функционального ремоделирования сердца, что способствует более эффективному выявлению СНсФВ. Однако низкий уровень согласованности этих шкал подчеркивает необходимость дальнейшего изучения лиц с СНсФВ с учетом их фенотипирования, что может способствовать разработке более упрощенных диагностических алгоритмов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Highlights</title><p>Highlights</p></sec><sec><title> </title><p> </p></sec><sec><title>Abstract</title><p>Abstract</p><p>HFpEF is a common disease. It has a poor outlook due to high death rates and complex drug treatments. The article describes a modern view of HFpEF's pathophysiology. It focuses on the causes of myocardial remodeling. It also presents new algorithms for diagnosing HFpEF. The triggers for HFpEF are activation of the neuroendocrine system, low-level inflammation, and myocardial fibrosis. The causes and mechanisms of HFpEF are complex. So, researchers must revise current diagnostic methods. New risk scales, HFA-PEFF and H2FPEF, aim to identify HFpEF patients. Researchers are still studying their effectiveness. Using both imaging and lab tests gives a complete view of heart changes. This helps detect HFpEF with greater accuracy. The low agreement between these scales shows a need for more study of HFpEF patients, given their phenotyping. This may help develop simpler diagnostic algorithms.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>Диастолическая дисфункция</kwd><kwd>Натрийуретический пептид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Heart failure with preserved ejection fraction</kwd><kwd>Diastolic dysfunction</kwd><kwd>Natriuretic peptide</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке гранта Московского центра инновационных технологий в здравоохранении № 2002-25/23.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">2021 Рекомендации ESC по диагностике и лечению острой и хронической сердечной недостаточности.
